In a method of replacing a machine part (5a, 5b) of a machine installation whose essential interconnected machine parts are arranged on a common base plate (7) which is secured in the ground by individual supports (8), a purpose-built base plate (7b) is produced in a preparatory phase, on an adjacent foundation slab (12), for the newly to be connected machine part (5b). On this base plate the machine part (5b) is provided with mountings, undergoes final assembly, is aligned and has all its functions tested. In a replacement phase, the machine part (5a) to be replaced is disconnected from the remaining machine part, its base plate section (7a) is servered from that (7) of the remaining machine part and from the individual supports (8) and it is displaced onto an auxiliary structure. The structural unit comprising the "machine part/base plate newly to be connected" (7b, 5b) is displaced by hydraulic means to take the place of the severed base plate. After the unit (5b, 7b) has received its final alignment, it is connected monolithically with the base plate section (7) of the remaining machine part (1-3) and the individuals supports (8).

Abstract

In a method of replacing a machine part (5a, 5b) of a machine installation whose essential interconnected machine parts are arranged on a common base plate (7) which is secured in the ground by individual supports (8), a purpose-built base plate (7b) is produced in a preparatory phase, on an adjacent foundation slab (12), for the newly to be connected machine part (5b). On this base plate the machine part (5b) is provided with mountings, undergoes final assembly, is aligned and has all its functions tested. In a replacement phase, the machine part (5a) to be replaced is disconnected from the remaining machine part, its base plate section (7a) is servered from that (7) of the remaining machine part and from the individual supports (8) and it is displaced onto an auxiliary structure. The structural unit comprising the "machine part/base plate newly to be connected" (7b, 5b) is displaced by hydraulic means to take the place of the severed base plate. After the unit (5b, 7b) has received its final alignment, it is connected monolithically with the base plate section (7) of the remaining machine part (1-3) and the individuals supports (8).
